Product details
Overview
MC9S08AC96CFGE from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller featuring a 40-MHz CPU core, 96 KB on-chip FLASH memory, 6 KB RAM, and integrated peripherals including dual SCI modules supporting LIN 2.0/SAE J2602, dual SPI, I²C, three TPM timer/PWM modules, 16-channel 10-bit ADC with temperature sensor, and KBI keyboard interrupt. It targets automotive body control, industrial sensor nodes, and low-cost embedded control systems requiring robust debug support and extended temperature operation.
For engineers reviewing the MC9S08AC96CFGE datasheet, MC9S08AC96CFGE pinout, MC9S08AC96CFGE application, or MC9S08AC96CFGE equivalent, this page delivers verified electrical specs, package mapping to 48-pin QFN (98ASA00466D), functional pin roles, real-world use cases in automotive LIN networks and motor control, and two validated alternative parts with documented technical and application differences.
Technical Context
The MC9S08AC96CFGE implements the enhanced HCS08 CPU core with linear address pointer and memory management unit for paged memory access. Its internal clock generation (ICG) supports crystal, resonator, external clock, or internally trimmed RC sources - enabling flexible timing without external components in cost-sensitive designs.
System-level protection includes COP watchdog with independent clock source, CRC module for memory integrity checks, low-voltage detect/reset/interrupt, illegal opcode detection, and master reset with POR. Power management supports Wait, Stop2, and Stop3 modes with sub-100 µA typical current draw in Stop3 - critical for battery-powered automotive and industrial applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | HCS08 8-bit core with 40-MHz max frequency and 20-MHz bus clock - enables deterministic real-time control at low power. |
| Memory | 96 KB FLASH (read/program/erase over full voltage/temperature range) and 6 KB RAM - sufficient for complex firmware with data logging and security features. |
| ADC | 16-channel, 10-bit SAR ADC with 2.5 µs conversion time, internal bandgap reference, and integrated temperature sensor - supports precision analog sensing without external references. |

The MC9S08AC96CFGE features an enhanced HCS08 CPU core rated for up to 40 MHz operation, with a corresponding 20 MHz internal bus frequency. This allows deterministic real-time execution of control algorithms while maintaining low power consumption - verified across the full –40°C to +125°C temperature range per Freescale's MC9S08AC128 datasheet Rev. 4.
Does the MC9S08AC96CFGE support LIN 2.0 protocol natively?
Yes, the MC9S08AC96CFGE includes two SCI modules explicitly qualified for LIN 2.0 and SAE J2602 compliance, providing hardware-level support for master extended break generation and slave extended break detection. This eliminates the need for external LIN transceivers in basic node implementations, as confirmed in the MC9S08AC128 data sheet section "Peripherals".
What package type and pin count does the MC9S08AC96CFGE use?
The MC9S08AC96CFGE is supplied in a 48-pin quad flat no-lead (QFN) package with exposed thermal pad, outlined under document number 98ASA00466D. This copper-wire package supersedes the earlier gold-wire variant 98ARL10606D, as documented in Freescale's QFN Addendum Rev. 0 (July 2014).
How much FLASH and RAM memory does the MC9S08AC96CFGE include?
The MC9S08AC96CFGE integrates 96 KB of on-chip FLASH memory and 6 KB of RAM. Both memory blocks support read/program/erase operations across the full operating voltage (2.7–5.5 V) and temperature (–40°C to +125°C) ranges, with security circuitry preventing unauthorized access - specifications confirmed in the MC9S08AC128 data sheet Rev. 4.
